The BOOX MAX 2 sadly doees not expose its full native resolution through the external monitor interface which is a real shame. Worse, none of the supported resolutions are integer fractions of the native resolution so scaling artifacts are unavoidable. It doesn`t even seem possible to sacrifice some border area and use a suitably-sized subwindow of the screen (e.g. FHD 1920x1080) without scaling. (If somebody knows better, please leave a comment)
Onyx pretends there is no problem and cheerfully tells frustrated users to adjust their OS theme and font sizes, over and over again [1]. Shame on them for ruining what could have been a great and unique feature. because wouldn`t it be for this problem, the MAX2 would finally be a decent sunlight-ready external laptop screen, at least for text writing and some light coding.
Well perhaps the problem is solved in the new MAX3 device.
Reg feedback for Onyx, you can try passing it to this YouTuber; he covers electronic shows world over and seems to have good relations with Onyx - https://mobile.twitter.com/charbax.
